[SOLVED] MIME type not recognised

Hi all,

I've noticed that the blender 3D modelling files (*.blend) I have on my computer are recognised by xdg-mime as being of mime-type application/octet-stream.

This is strange, as I have checked the /usr/share/mime directory where the system settings are in terms of mime types, and an "x-blender" mime-type exists where the glob pattern is set to: "*.blender", "*.blend", and "*.BLEND".

Given the extensions of my files, I wasn't sure why xdg-mime is not picking up the files as application/x-blender instead.

This is quite annoying- does anyone know any reason why this might be occuring?

I have tried running

$ update-mime-database /usr/share/mime

in case these entries were not reflected by xdg-mime or something, but that didn't make a difference.

This is the entry for the application/x-blender mime type in /usr/share/mime/packages/freedesktop.org.xml:

  <mime-type type="application/x-blender">

I'm sure I'm missing something stupid. Thanks in advance!

Re: [SOLVED] MIME type not recognised

In most cases, xdg-mime uses "file -i" to get the mimetype. "file -i" uses its own internal mime database that seems to be missing blender support.
You can install the package perl-file-mimeinfo, then the "mimetype" tool is preferred which does rely on the definitions in /usr/share/mime and should work.

There are two special cases: For gnome xdg-mime uses "gio info", and for kde "kmimetypefinder".

Re: [SOLVED] MIME type not recognised

@progandy, thank you for your reply. I have just installed perl-file-mimeinfo and everything is working as expected! I will mark this thread as solved.
